Wondering along the path from Althorn to North Fambridge in Essex. Skylarks! Their contented never-ending songs, wheeling about slowly in the warm thermals somewhere, high above. Almost as far as the eye can see, a vast waist-deep plantation made of millions of waving stems and leaves is catching the breezes, shushing and sissing in sympathy with the moving air. This, is open country, crossed by the rippling River Crouch on its way to the North Sea.

A blackbird sings, out over the swirling water at Wrabness. It's perched high up in a gnarled tree, leaves catching the softly flowing breezes. It's the closest of a whole bank of trees to the estuary water, and the last before the mud of the exposed shoreline begins. The tide's just turned. A warm, quiet summer afternoon, and nobody's about.

Midday in August. Sun beating down. Strong, radiant heat. It's making the crickets cricket in the grass beside the marina. Cool, deep water, glinting, with lines of sailing boats, all moored up. Their masts knock in the wind, and sometimes sound like bells. Seagulls. Out over the basking River Crouch, 

Inland, across the other side of the vast county of Essex, the churchyard of St Mary's Gilston is at rest. It's unusually peaceful because it's under a very quiet sky. Rare. A phenomenon of 2020 and 2021. A secluded spot, where walkers can stop, ease their feet on the wooden bench, and listen to wood pigeons cooing on the warm slates of the church roof.

Towards London, where the last piece of Essex country blends into the series of lakes that make the Lee Valley Park, the night is coming. The paths, usually busy with people enjoying their freedom, are empty. No more bikes and scooters. No more barking dogs. No more chasing kids with trikes and ice creams. Just dark bush crickets under the hedgerows, and swans, slowly swimming over still, twilight water. And the echoing hoots of owls.
